WROUGHT-METAL BUCKLE.

Specification of Letters Patent.

Patented June 19, 1906.

To all whom, it may concern.-

Be it known that we,-GHARLEs S. HUNT- INGTON and ARTHUR S. HUNTINGTON,citizens of the United States, residing at Omaha, in the county ofDouglas and State of Nebraska, have jointly invented certain new anduseful Improvements in WroughtMetal Buckles, of which the following is aspecification.

This invention relates"to improvements in buckles; and it has for itssalient objects to rovide a strong, sightly buckle which can be moreeconomically manufactured than could be done by previouslyknown methods.to provide a buckle of such construction that the metal may be workedcold, thus avoiding the expense and objectionable elfects due to heatinthe metal, to provide a construction which ends itself to readyformation by automatic machinery, and in general to provide improvementsin devices of the character re ferred to.

To the above ends the invention consists in the matters hereinafterdescribed, and more articularly pointed out in the appended claims. j

The description will be better understood by reference to theaccompanying drawings, inwhich Figure 1 is a plan view of a blank bentinto shape to form a buckle and ready to be struck with theswaging-dies. Fig. 2 is an edge view of the same. Fig. 3 is a plan viewof the finished buckle. Fig. 4 is a transverse sectional view taken online 4 4 of Fig. 3. Fig. 5 is a erspective view showing one side of thebuckle seen in Figs. 3 and 4 forced asunder, so as to show more clearlythe form of joint by which the parts are united.

In carrying out our invention we preferably utilize drawn wire or rodmetal, although the blanks may be formed of wrought metal cut intosuitable strips. These blanks are so formed that when the buckle-framehas been brought to its approximate shape or outline the terminalportions of the blank overlie or overlap other portions of the frame insuch manner that the ends may be united by a single stroke of asuitableswaging-die. For example, in forming the buckle-frame shown in thedrawings, which buckle is of that type having a double loop andcross-bar, the blank 1, provided with obliquely out oif or beveled ends2 2, is shaped into an approximately S form and the terminal portionsextended so as to overlie and extend slightly beyondthe angles 3, formedat the junction of the crossbar portion 4 with the side-bar portions 5and 6, respectively. Theblank is so cut that the inclined ends 2 2 bothwhen the blank is straightt. e., before shapingand also after beingbrought into shape in readiness to be struck with the die, from which itresultsthat of the blank lie in planes coincident with the innerboundary of the outer frame. The blank having been thus preliminarilyshaped on a suitable former, it is placed between dies and struck withsuflicient force to crush the overlapping portions together, so that theside members of the buckle-frame are united to form a continuousring-frame of substantially uniform and uninterrupted continuity. Theparts are so crushed into each other that they are actually interlockedand rigidly united independently of molecular unionthat isto say, themetal is cold-swaged tothe extreme points are substantially-parallelgether in the preferred construction and accordingly the joints are notwelded.

By reference to Figs. 4 and 5 it will be seen that the obliquely-cut-olfpoints 2 2 are swaged into the angle portions 3, and the extremities ofthese points lap around the inner side of the ring-frame so as to bothhook over the cross-bar 4 and merge into the side-bar portions 5 and 6.Subsequent metal coating, such as nickeling or galvanizin conceals thepresence of the joints when it is desired to furnish a buckle morefinished in appearance. Of course the swaging to gether of the parts inthe manner described cannot result in a joint the parts of which are ofuniform cross-sectional area, but the slight enlargement of the frame atthe points of union is almost imperceptible and not at allobjectionable. The tongue, which is indicated in position in dottedlines in Fig. 3, is subsequently fastened to the cross-bar in the usualmanner. Various minor changes may be made in the structure illustratedand described herein without departing from the substanceof ourinvention, as will be obvious to those skilled in the art.

a We claim as our invention 1. Y A buckle-frame comprising a strand ofwrought metal, having its central portion arranged to form a cross-barand its end portions formed into reversely-disposed loops united withthe ends of the cross-bar portion,
